This patch set:
- Fixes GRE6 to process translate flags correctly from configuration
- Adds support for GSO and GRO for ip6ip6 and ip4ip6
- Add support for FOU and GUE in IPv6
- Support GRE, ip6ip6 and ip4ip6 over FOU/GUE
- Fixes ip6_input to deal with UDP encapsulations
- Some other minor fixes
Tested:
Tested a variety of case, but not the full matrix (which is quite
large now). Most of the obivous cases (e.g. GRE) work fine. Still
some issues probably with GSO/GRO being effective in all cases.
